  • the rafters 10 may vary according to the design of the building, as known to those skilled in the art, and such alternatives should be considered within the scope of the present invention.
  • FIGURE 3 is a perspective view of a single pan tile 30.
  • FIGURE 4 is a sectional view thereof taken along line 4-4 in Figure 3 .
  • the pan tiles 30 are generally rectangular in shape with a generally U-shaped cross section.
  • the pan tiles 30 are each wide enough to overlap the pair of adjacent rafters 10 on the building on which they are used.
  • An average pan tile 30 in one embodiment is approximately 18 inches long and 8 inches wide, although these measurements will vary according to the requirements of a specific installation.
  • the pan tiles 30 may be tapered.
  • the pan tiles 30 each have a concave body 32 formed of a light transmitting material.
  • the concave body 32 has a top surface 34 and an opposed bottom surface 36 connected by a perimeter edge 38.
  • the perimeter edge 38 may include a top edge 40, and opposed bottom edge 42, and side edges 44.
  • the top surface 34 faces upwardly when the concave body 32 is installed on the roof, and is concave, preferably with a generally U-shaped cross section.
  • the bottom edge 42 may merely follow the top surface 34 (convex) so that the concave body 32 has a generally equal cross section; however, other shapes, and varying thickness, may also be utilized.
  • side edges 44 are described, the term "edge” is hereby defined to include alternative embodiments.
  • the edges of two or more pan tiles 30 may be integrally formed, so that a single integral piece may provide multiple pan tiles 30.
  • the pan tiles 30 may each have a longitudinal axis 46 that is generally parallel to the side edges 44, or to the longitudinal center of the tile (if the edges are tapered). Each pan tile 30 may further have a U-shaped cross section when cut perpendicular to the longitudinal axis 46 (the term "U-shaped” is hereby defined to include equivalent shapes, such as V-shaped, and similar curved or formed shapes). When installed, the pan tiles 30 may be arranged in aligned courses 60 wherein each of the aligned course includes a group of pan tiles 30 that overlap along a common longitudinal axis 46, and wherein an overlapping course 62 of the convex roof tiles 50 overlaps the side edges 44 of two adjacent aligned courses 60 of the pan tiles 30.
  • the perimeter edge 38 may include a receiving chamber 66 for receiving a light generating element 68.
  • the light generating element 68 may be mounted or otherwise positioned in the receiving chamber 66 to direct generated light into the concave body 32 of the pan tile 30 to illuminate the pan tile 30.
  • the receiving chamber 66 is positioned in the top edge 40.
  • the receiving chamber 66 may be positioned elsewhere in the pan tile 30.
  • the light generating element 68 may be otherwise positioned adjacent the perimeter edge 38 so that light is directed into the pan tile 30, as described.
  • the light generating element 68 may be, for example, an LED strip that includes light emitting diodes (LEDs) 70 electrically connected and mounted on a backing 72 (e.g., rigid semiconductor, flexible base, etc.). While LEDs 70 are used in the current embodiment, other illumination materials may also be used (e.g., incandescent bulbs, phosphorescent/ luminescent material, and other materials or devices that can provide the necessary illumination).
  • LEDs 70 are used in the current embodiment, other illumination materials may also be used (e.g., incandescent bulbs, phosphorescent/ luminescent material, and other materials or devices that can provide the necessary illumination).
  • the pan tiles 30 are positioned between the rafters 10 such that the convex side of each pan tile 30 fits between the pair of adjacent rafters 10 and faces downwards towards the rafters 10.
  • Each side of each of the pan tile 30 is then attached to one of the rafters 10 with a fastener (e.g. nails, screws, other suitable fastening device or method).
  • the pan tiles 30 are arranged in overlapping courses 62 down the length of the roof. If the top edge 40 of the pan tile 30 is somewhat larger than the bottom edge 42, the pan tiles 30 are easier to overlap, although this feature is not required.
  • Each of the pan tiles 30 is made of a light transmitting material, such as a polycarbonate or polystyrene material, although other plastics, resins, or other suitable materials may also be used.
  • the material must be at least partially translucent, and the material is transparent in acceptable embodiments.
  • the material is colored or tinted in other embodiments, providing a desired character and diffusion to the light entering the building.
  • the illuminated exterior roofing structure 20 further includes a plurality of convex roof tiles 50.
  • the convex roof tiles 50 may be traditional tiles (e.g., clay, terra cotta, stone, etc.) such as those commonly used in the construction of residential homes and apartments.
  • the roof tiles 50 may also be constructed of a more lightweight material (e.g., polycarbonate, polystyrene, plastic, resin, etc.) that has an integral color, or is painted, coated, or otherwise treated to resemble traditional clay roof tiles.
  • the roof tiles 50 have opposite edges 52 and are adapted to be mounted on top of and partially cover the pan tiles 30 such that the edges overlap the sides edges 44 of the adjacent pan tiles 30.
  • the roof tiles 50 are fastened to the rafters 10, preferably with the fasteners 64.
  • These convex roof tiles 50 are the only part of the invention that is plainly visible to a casual observer looking at the exterior of the building, so the roof tiles 50 provide an aesthetically pleasing exterior that covers the less visually pleasing look of the pan tiles 30.
  • the pan tiles 30 and the roof tile 50 are positioned perpendicular to and across the skip nailers 12 rather than parallel to and between the rafters 10.
  • the pan tiles 30 are fastened to the skip nailers 12 with the fasteners 64.
  • the roof tile 50 may also be fastened to the rafters 10 with the fasteners 64.
  • the pan tiles 30 and the roof tiles 50 are arranged in overlapping courses 62 down the roof.
  • the pan tiles 30 and the roof tiles 50 may overlap enough so that the fasteners 64 are covered by the next higher pan tile 30 or roof tile 50, thereby both improving the appearance and preventing leakage.
  • the illuminated exterior roofing structure 20 further includes a power distribution network 74 for providing electric power to the light generating elements 68 of the pan tiles 30.
  • the power distribution network 74 may include electrically conductive wires that are electrically connectable to a power source 76 (e.g. battery, power grid, power generation device, etc.).
  • the electrically conductive wires may be individually connectable to the power source 76, or may be daisy-chained to form the network. While one embodiment of the power distribution network 74 is illustrated, those skilled in the art may devise many alternative embodiments that provide the necessary power to the pan tiles 30.
  • the first step of this method is to provide the illuminated exterior roofing structure 20 as described above, including both the pan tiles 30 and the convex roof tiles 50.
  • a plurality of the pan tiles 30 are then fastened to the rafters 10 (and/or to skip nailers 12 or similar structures) near the eaves of the roof, such that the pan tiles 30 are generally parallel, either adjacent each other or spaced a short distance from each other.
  • the pan tiles 30 span the space between the pair of rafters 10, with the convex side of each pan tile 30 adjacent to the rafters 10.
  • the pan tile 30 may be fastened to the rafters 10 with a fastener 64 such as a pan screw, nail, or similar fastener. Additional pan tiles 30 are then added to the illuminated exterior roofing structure 20 in overlapping courses 62 until the roof is covered with spaced rows of pan tiles 30 running perpendicular to the edge of the roof. In the embodiment of Fig. 5 , the pan tiles 30 are positioned across the skip nailers 12, as described above. Alternative arrangements may be utilized, depending upon the roof structure that is preferred, and such alternatives should be considered within the scope of the present invention.
  • the light generating elements 68 of the pan tiles 30 may be electrically connected to the power source 76, or at least to the electrically conductive wires that will later be connected to the power source 76.
  • the roof tiles 50 are then fastened on top of the pan tiles 30 such that the edges of the roof tiles 50 overlap the sides of the adjacent pan tiles 30.
  • the roof tiles 50 may be fastened to the rafters 10 with the fasteners 64. Cement may also added to further strengthen the roof and secure the roof tiles 50 to the roof. Additional roof tiles 50 are added to the illuminated exterior roofing structure 20 in overlapping courses 62 until the roof is covered with spaced rows of roof tiles 50 running parallel to and overlapping the rows of pan tiles 30.
  • additional roof tiles 50 are added to the illuminated exterior roofing structure 20 near the eaves of the roof, to improve the aesthetics of the illuminated exterior roofing structure 20.
  • the pan tiles 30 and the roof tiles 50 may be positioned concurrently, working up the roof, as is known in the art.
  • pan tiles 30 are not constrained to any specific shape except by the convenience of the roofing installer.
  • Using a pan tile 30 having a different shape is equivalent to the current invention if that pan tile 30 is light transmitting and capable of being covered with traditional pan tiles 30.
  • the pan tiles 30 could be formed as a large single sheet of light transmitting material.
